A match of Sherwin Williams 42104 is a cool blue-green with moderate softness, reading like a restrained aqua or teal rather than a bright turquoise. Its mid-range lightness and low-to-moderate chroma give it a calm, slightly gray cast that can look clearer on smooth surfaces and more subdued on textured ones.

MyPerfectColor custom spray paint matched to 42104 is useful for parts and accessories that need a coordinated blue-green finish without looking overly vivid. Common spray-paint applications include HVAC vents, speaker grilles, switch plates, brackets, shelving supports, railings, shutters, PVC trim, mailbox parts, hardware, and small furniture accents. It can also be used on metal, plastic, wood, or previously coated pieces after proper surface preparation.

From a technical standpoint, this is not an especially high-chroma color, so coverage is usually more manageable than with very bright colors. Even so, finish, substrate, and film build can change how blue-green the color reads, and thin application over a dark or uneven base can leave contrast visible. Sheen differences can also be noticeable on smooth fixtures and hardware, so consistent prep and application help the color read evenly.

Frequently Asked Questions About Match of Sherwin Williams™ 42104 *

How do I confirm Sherwin Williams 42104 before ordering a MyPerfectColor match?

Confirm Sherwin Williams 42104 from a physical swatch or another known existing color reference from the original brand, not from a screen alone. MyPerfectColor makes a custom match to the selected brand color reference, so the first step is making sure 42104 is the exact target you want.
